After two weeks in preseason camp, Tulane Coach Bob Toledo said they still have not determined their five best offensive linemen.

Projected starting left tackle Pat Husain was demoted to second-team in Friday morning’s practice and Harris Howard, the projected starter at left guard, got reps at left tackle.

“We’ve moved guys around, we don’t have a lot of linemen,’’ Toledo said. “So we need to find the best five that can play and then the other six or seven will be the backups.’’

Toledo said Harris has played well at left guard but said their left tackle (Husain) has not been performing up to expectations.

“We’re trying to motivate him or he’ll be a backup,’’ Toledo said.

The Green Wave will scrimmage Saturday afternoon at their practice field. . . . .OL Ben Stone, LB Steven Funderburk, DE Desman Moses and S Taylor Echols are out with concussions. “Everyone in the country got the same problem,’’ Toledo said. “Syracuse has only nine offensive linemen, their left tackle got a concussion. We used to have headaches. We don’t have any headaches anymore, we have concussions.’’
